Finding water in your basement can make your stomach sink. You don’t know where it came from, you don’t know how to repair it, and you have no idea how much it will cost. 

A customer in Ajax, Ontario, discovered water on his basement floor. He searched the basement and found a few foundation cracks that were allowing moisture through. Concerned for his home’s wellbeing, he decided to reach out to a few contractors. He wasn’t confident until he discovered Clarke Basement Systems and met with System Design Specialist Chris Luke. 

Chris showed the homeowner our FlexiSpan® Crack Repair System, and he was happy to have a proven solution offered finally. Foreman Mark Dougherty started the repair by injecting a polyurethane sealant inside the crack. More polyurethane was used to seal the exterior, and a drain is placed on top. For added security, an in-floor drain was installed.

The customer is very pleased that his basement is dry. He appreciates the hard work and honesty of Mark and Chris and is confident that the repair will last.

A basement in Ajax, ON, had an issue inside the laundry room. Three holes were leaking damaging the finished floor and walls.

The area is now dry while being a safe and healthy space.

There is a slew of things that can go wrong in our homes. Our dishwasher could leak, a storm could knock off a few shingles, and for some people, a crack in the foundation can lead to a wet mess.

A customer in Ajax, Ontario, had a small landing under their stairs where they would store items. It was a great little storage place for them to utilize, until one day they came down to find their belongings soaked. A crack had formed in the foundation wall, and water was seeping in. Concerned for the worst, they reached out to Clarke Basement Systems.

System Design Specialist Chris Luke met with the anxious customer and addressed his concerns. The customer was thrilled that we had the perfect solution to his problem, and Foreman Mark Dougherty was sent to repair the crack.

Mark used our FlexiSpan® Crack Repair System to seal the crack, starting with several injections into the crack. He sealed the outside and created a drain in the concrete floor, giving water an easy way to seep back into the ground.

The customer is happy that he no longer has to worry about his belongings getting wet. His floor is dry for good, and he can finally walk into his basement wearing socks again!

Moisture loves trying to find a way into our homes. A small crack or broken seal can be a gateway for moisture, leading to frustration and possible damage. Ontario homes are especially prone to this problem, often caused by the natural curing process of concrete. These cracks don’t usually threaten the foundation, but they can lead to water issues. 

A Brampton, Ontario customer was dealing with this problem in his home. A small crack in the wall was leaking water into his basement, damaging the walls and floor. Frustrated and desperate to prevent any further damage from occurring, he reached out to Clarke Basement Systems.

Ron Monk, System Design Specialist, met with the customer to discuss a solution. Ron recommended a FlexiSpan® Crack Repair System to fix the problem, and job foreman Mark Dougherty installed the system.

FlexiSpan® is a warrantied, high-viscosity polyurethane polymer. It gets deep in the crack to form a durable seal, ensuring water stays out. A layer of foam is then placed overtop of the crack before being covered with a polyurethane sealant. It’s extremely flexible, giving it the ability to stay bonded even as concrete expands and contracts. The polymer stops 95% of previous moisture seepage, and any moisture that does get through is sent downward to a drain system.

After the FlexiSpan® system was installed the customer was happy that no further damage would occur, and they could finally put the walls back together. Their basement was clean and dry once again.

Homeowner in Oshawa, ON, was stressed out about the water seepage that was causing damage to the finished walls and carpet in their home. They could no longer use the space and needed it fixed before it continued to cause any further damage! 

They contacted Clarke Basement Systems and scheduled an inspection with System Design Specialist, Ron Monk. Ron Monk attended the home and concluded that cracks in their foundation walls caused the water seepage. This usually happens when it is a poured concrete wall.

Ron Monk concluded that to seal the leak properly, we would need to install our patented FlexiSpan® on the homeowners poured wall foundation.

With the plan set in place, Installation Foreman, Mark Dougherty and his team got to work. They removed the existing drywall and insulation of the home, then installed FlexiSpan® on the wall foundation.

When the work was finished, the homeowner was ecstatic that there would be no more water seepage and that they are guaranteed with the 25-year warranty. They can now renovate their home and not have to worry about any potential damage thanks to Clarke Basement Systems.

A customer in Brooklin, Ontario, had just this problem when he found water in his basement. The water was beneath the laundry tub, so he figured that the tub was leaking. It wasn’t until further inspection that he discovered a large crack behind the sink. He thought about patching it himself but decided to give Clarke Basement Systems a call instead. 

System Design Specialist Chris Luke met the customer and inspected the home. The customer was impressed with our repair method, and a date was set for the repair.

Foreman Mark Dougherty used polyurethane to seal the interior and exterior of the crack. An in-floor drain was dug to prevent any new cracks from leaking onto the floor, and an additional drain was installed on top of the sealant.

The customer can’t wait to do his laundry in a dry environment. He’s thrilled that the crack is sealed and is happy he decided to go with us rather than doing it himself.
